The Grinder is added by the MineFactory Reloaded mod. Like most MFR Machines, it runs on either Buildraft or Industrial Craft 2 power.

The Grinder will slaughter any mobs or animals (including cats but it will not kill players, baby animals and Iron Golems) in a 5x5 (front) area and automatically dump the harvested materials out the back or into an adjacent chest or buildcraft pipe. Mobs will also drop Mob Essence, which will be automatically pumped from the Grinder into an adjacent Wooden Waterproof PipeAuto-Spawner or an Auto-Enchanter.

Grinders can be turned using a Precision Sledgehammer or an OmniWrench

Like all Minefactory Reloaded machines the grinder can be turned on/off using a redstone signal.


The Iron sword is an Invar sword in newer recipes
